389 * @get_per_queue_coalesce: Get interrupt coalescing parameters per queue.
390 * It must check that the given queue number is valid. If neither a RX nor
391 * a TX queue has this number, return -EINVAL. If only a RX queue or a TX
392 * queue has this number, set the inapplicable fields to ~0 and return 0.
393 * Returns a negative error code or zero.
394 * @set_per_queue_coalesce: Set interrupt coalescing parameters per queue.
395 * It must check that the given queue number is valid. If neither a RX nor
396 * a TX queue has this number, return -EINVAL. If only a RX queue or a TX
397 * queue has this number, ignore the inapplicable fields. Supported

401 * settings. The %cmd and %link_mode_masks_nwords fields should be

414 * cannot use the standard PHY library helpers.
416 * All operations are optional (i.e. the function pointer may be set
417 * to %NULL) and callers must take this into account. Callers must
418 * hold the RTNL lock.
420 * See the structures used by these operations for further documentation.
421 * Note that for all operations using a structure ending with a zero-
422 * length array, the array is allocated separately in the kernel and
423 * is passed to the driver as an additional parameter.
425 * See &struct net_device and &struct net_device_ops for documentation
426 * of the generic netdev features interface.
